Application filed September 3, 1909. Serial No. 516,125.

To all whom 'it may. concern:

Be it known that I, OREVELL C. REEVES,

ment for weighing scales which 4will facilitate the uniform weighing of goods in in stances Where a certain exact amount of weight is established and successive quantities of goods or packages containing 4goods are required to have just this weight, as for example in handling tobacco according to government regulation in the matter of. correct Weight as related to the internal revenue tax. This sort of Weighing has ordinarily been done on even-balance scales the operation of which is necessarily slow as compared with the operation of yscales which vautomatically denote weight upon the placing of goods thereon.v In the use of the automatic scale, however, there would ordinarily be no assurance that the operator was uniformly weighing thegoods or observing the established weight as it would be left to him to carry in mind this established weight which might very well run to fractions and so in repeatedly noting registrations of the indicating mechanism (which necessarily would comprise' relatively movable parts, one having rather fine graduat-ions,) mistakes would bever likely to occur and fui-then more there might be either lack of uniformity in weighing or uniform under or verweight from design on the part of the operv ator.

the registering of a single mark with' another, one being, e. g. on a movable part offtheweighing apparatus and thel other on a member adjusted by some person in authority who holds the key ,by which to man of the room .in which. weig' done would establish the crepe ment by the use of his key nue. all n ator would be called upon tc do 'aramid acto weigh to this adjustment and it would `be out of bis power to change the adjustment.

In the drawings which .accompany and form part of this specification Figure represents'in front elevation a scale of wellregulate the adjustment. Thus' the' foreknown type, equipped to carry out the pres' ent invention, a portion of the inclosing casing or housing of the scale being represente:` in section; Fig. 2 is a vertical cross-section taken on line 9.--2 of l; and 3 illustrates in perspective a part belonging to the equipment provided by the present invention.

The type of weighing. scale here shown is that known on the market as the Toledo and disclosed in numerous prior patents of which it will suffice to mention De Vilbiss Reissue No. 12,13? of July 28, 1903. The scale lcomprises the supporting base A in which is fulcrumed a weighing beam B supporting a goods receiver here shown in the form 'of a scoop C;' a pendulum D fulcrumed in a housing E erected on the base A and connected to the beam B by a strap F overlying and secured to an eccentric disk G on the pendulum hub. The upper por- 'of this sort as ordinarily' constructed such weight graduations copen'ate with an index hand or pointer secured to the pendulum hub or journal and the weigl in by simply )lacing goods in tl K or on a p atform and noting L, n graduation with which such. pointer regis ters or most nearly'registers when the vibration ceases, means being ordinf vided such. as a dash pot `to lessen ui. In carrying out the present invention the purpose is-not to so employ the weight graduations, but they are used lmerely as a means of adjusting an auxiliary indicating device. This is here shown in the form of an arm J e;;".en`ding upwardly within the housing E behind the platoI H and being bent over the top edge of said plate as shown in Fig. 2 and then down in front of the saine to the line of weight graduations as shown in Figs. l and 2. Upon this front downwardly extending portion 7' of said arm is a mark ,7" running tothe bottom edgev and adapted toregisterawith any one of the graduations-ff." The lower end oi' the arm J is fixedly secured as by a screw y'z to a stub shaft or rotary plug J" journaled in'a barrel K secured in the rear side of the of the plug J is formed to receive the bits of a key L, the latter adapted to be inserted through the cross slot Z3 oi' a disk K loosely mounted in the barrel K and confined against the shoulder thereof by a iange le of the barrel. It will be seen that by inserting the key through the slot and turning it until the bits register with the correspondingly formed outer end of the plug J and then thrusting the key farther,

inward it will be engaged with the plug so as to rotate-the latter and thereby the arm J. Thus the foreman or other person -in authority -lwho carries the key can adjust the said arm to cause its niark to register with any desired graduation of the segmental series I, the key being then with.- drawn so that the auyustment cannot be tampered with. 0f course the plug J will be journaled in the barrel K with suliicient friction to prevent the arm J from having its adjustment accidentally changed. The front of the housing E is closed, the lower part by a plate E and the upper part by a glass E2 so that the arm cannot be reached from the front.

. An index arm or hand M is employed somewhat similar to that heretofore used, .sa-id hand being secured to the hub of the y pendulum but this hand does not have a pointer as is usually the case. It extends to "the outer curved line along which the y A. weight graduations are marked and has a y5c?fstraight or slightly curved end edge and is inscribed with a line m running to such edge and' adapted to register `with the line or mark j uponthe frontportion 1" oi' the before-mentioned arm J. When so registering. with the.. arm J the hand M covers the Weight graduation with which the mark y" is registering.

It will be obvious that with an arrangement .such as above described, the foreman or other person in authority having adjust ed the arm J to register its mark y" with a certa-in uWeight graduation of the series I, all that is required of the operator is to weigh successive quantities of goods causing the mark m on the arm M to register with said mark j. This insures uniformity in the weighing and observance of the proper weight, putting it beyond the operator to err through not carrying in mind the proper Weight or to weigh incorrectly designedly. lf his weighings are wrong he cannot make the excuse that he did not have the correct weight in mind. Furthermore, it is out of his power to set the scales for. the wrong weight. n

While the invention is here shown applied to a certain ywell-known type of automatic :weighing scales, it is to be understood that housing as sh'own in Fig. 2. The outer end the invention may be carried out with other types of weighingscales and that it is not limited to the particular type here shown. Neither is it necessary that the precise construction of auxiliary registering means be employed.

What is claimed is:

l. The'combination with indicating means of weighing scales comprising relatively movable members one having weight graduations; of an auxiliary indicating device adjustable with reference to such weight graduations and adapted to register with the other member of the tiret-mentioned indicating means, a rotary plug frictionally held in adjustedposition to which the auxiliary indicating device is secured, such auxiliary indicating member being in the formi of an arm secured to the rotary plug the latter formed to receive the bits of a key.

2. In weighing scales the combination or" movable weighing parts including an oscillating member, a iixed part bearing a segmental series of weights graduations con centric with said oscillating member, an indicating hand secured to the latter and extending across the series of weight graduations, and an arm journaled concentrically with said oscillating member and marked to register with any one of the weight graduations, the said index hand being marked to register with said arm, a rotary plug-frictionally held in position to which thc arm is secured and which is adapted to receive thebits of the key.

3. In weighing scales the combination of .a suitable support-ing base and housing, a

Weighing beam, a goods receiver thereon, an oscillating member connected to said beam, load-counterbalancing means, a plate fixed in the housing and bearing on one side a segmental series of weight graduations, an

index hand secured to said oscillating me1n-- ber and extending across the ronto'f said plate over a series of weight graduations, an arm extending in the rear of the plate and having an end portion carried in :t'ront` of the same to the line' oweight gra'duations thereon, a rotary plug to which said arm is Secured, and a' barx'el Secured o ik@ imi5- ing and nwhich said plug is journaed, 'the latter` adapted t0 be engaged by the bits .of a key for turning it and adjusting the arm and the latter having on its front portion ,a mark 4to register. with any one of the Weight 'gadufzvtionsmgnl Ythe index hand having a mark to @gister Wiwit @Haai-d 'OREVELL C.
